Sherrod Brown, the top Democrat on the Senate Banking Committee, called on the Trump administration Monday to consider barring Equifax from entering into any government contracts, the latest in the fallout from the credit reporting firm's massive data breach.

The Ohio senator asked the Treasury Department to review whether the firm's breach, which compromised the information of 145.5 million people, could constitute grounds for "debarment," which would prevent the company from winning or renewing contracts with the government.

"This simply is not a company that deserves to be trusted with Americans' personal data or taxpayer dollars," Brown wrote in a letter to Treasury debarment official Iris Cooper. His letter argued that the breach shows that Equifax is too out-of-control to be trusted with government contracts.

Brown's letter was released shortly after the Social Security Administration contracted with Equifax to help manage an online portal for beneficiaries.

Last week, Republicans criticized the IRS for awarding Equifax a short-term contract to protect the confidentiality of taxpayers. The company faced a series of hearings on Capitol Hill to face lawmakers with questions about the breach.
